ABSTRACT:
To down size a distortion-correcting circuit. In the case of a distortion-correcting circuit1, a basic-wave-amplifying section10and a distortion-extracting section20have the same circuit configuration. Therefore, the basic-wave-amplifying section10and the distortion-extracting section20have almost equal input impedance and output impedance and make it possible to distribute and synthesize signal powers without using any power distributor or any power synthesizer. Moreover, because the distortion-correcting circuit1is constituted by only a transistor, a resistance, a capacitor, or an inductor, it is easy to downsize the circuit1and constitute the circuit1into an integrated circuit. Therefore, a characteristic of the basic-wave-amplifying section10and that of the distortion-extracting section20are further similar to each other and it is possible to more properly distribute or synthesize signal powers without using any power distributor or any power synthesizer.
